Giovanni Grassi. Portrait of Giovanni Batista Grassi (1854-1925),Italian zoologist and malaria pioneer. In 1889-90 Grassi suggested that different species of the Plasmodium protozoa caused different varieties of malaria. In 1898 he demonstrated that only the Anopheles mosquito could transmit malaria to humans and in 1900 he proved that Anopheles maculipennis actually did. In 1900 he published his results in 'Studies of a Zoologist on Malaria'. Image from 'La Conquete Du Monde Invisible' by Giuseppe Penso | |
